loin the nature of an improvement `on the Letters Patent of the'United States granted to us November 8, 1904, Number 774,492, for an improvement in car trucks, in which the wheel-pieces, the endpieces, and the (respectively I-shapedv in cross section) of the truckframe are combined, with or Without gussets at their junction to each other, in a single piece of vcast metal, preferably -\cas`t steel;. ,20 and our invention has 'forI its object to increase' the strength and rigidity of the truck-frame and amplify its adaptability to the exigency of service.

The' invention consistsV in features of nov'- 25 elty as .hereinafter described and claimed,

reference-being had to' the accompanying drawing forming partlpf this specification, VWhereon, l

patent, except that they are 'different therefrom in cross section, to wit, respectively, box, L, and channel-shaped, in lieu of I-shaped, as contemplated and specified on page 2, lines 1 to 4 in the specification of the said patent; and that the horns vof thev pedestals for the journal boxes are preferably omitted as an integral feature of the wheel-pieces..

Each end-piece 1 is united to the corre` spending cross-piece orvoutside transom 4, at each side of the longitudinal center of the truck-framed, bya longitudinal mem-- A CORPORATON OF NEW' ber 5 which is parallel to the wheel-piece 1 at a suitable distance therefrom, while the middle cross-pieces or transoms 3 are similarly united to each other by longitudinal members 5 which are preferably alined to the members 5 and adapted at the top for the attachmentthereto of a brakehanger bracket, the members 5 and 5 being in the present case channel-shaped in cross section and suitably shaped on v their'underside to form the axle-guards of the truck. By unit- 5- and 5 in this .manner integrally at theirv ends to the cross members 2, 3, and 4, "i-nter mediately tothe wheel-pieces 1, the truck- .frame a is reinforced and its rigidity increased. v

Onthe outer side of each longitudinal member or axleguard 5, preferably,between and uniting its top and bottom flanges, is

formed an upright bracket or Web 6 for the .attachment thereto' by bolts (or screws) 7 erably, its outer side, by an upright web 10 which is integral at its junction with and strengthens the wheel-piece .1 thereat.

For obviating the wear and increasing the durability olf the spring-beam and brakehangerbrackets 11, 11', which are integral with the body of the lframe a, 1l', 11', is formed with a preferably circular configuration andl arranged in a similar opening transversely therethrough, and'in this opening is cast a metallicv bushing l2 Whicl'iis adapted internally to forma bearling the longitudinal members or axle-guards each bracket in g for the-corresponding hangerpin, where'- by when the bearings 12 become Worn they can be removed and replaced Without 'injury' to the brackets 11, 1l', and body of the frame a.

It is here noted that if desired each outer cross-piece or transom lsmay be united tothe adjacent inner cross-piece or transoin 3 by a member m, preferably alincd' tov transoms, a member integral with and uniting-each end-piece to the adacent outer cross-piece or transom', at each side of '(lesciibed, the combination with the brakethe longitudinal center of the frame, and a bracket integral with the said member and adapted for' the attachmentthereto ofa bar for carrying an electric light device, substantially as described.

2. In a car truck frame of'the character j described, the combination of the Wheelpieces, the end-pieces, the cross-pieces or and uniting the inner cross-pieces or transonis to leach other at each side of the longitudinal center of' the ranie, the said members being adapted to form guards for the axle of the middle Wheelsof the truck, suliistantially as described.

3. In a car truclcframe of the character described, the combination of the Wheelpieces, tlieend -pieces, the cross-pieces or transoms, a member integral with and uniting each end-piece to the adjacent outer cross-piece or transom at each side of the longitudinal center of the frame, and a meinber integral with and uniting the inner cross-pieces or transoms to each otherat each side of the said center', the said members 'being adapted to form guards for the axles y pieces having iespectively, al recess in its underside for the clearance of the equalizerbar, of an upright web adapted to close one side of the said recess and integral with the said piece, substantially as described and for the purpose set forth. f 5. In a car truck frame of the character described, the combination -With the springbeam brackets cast integral Withithe vframe, and having respectively, an opening transversely therethrough o anietallic bushing cast in and removable from the said opening and adapted to form a bearing fortlie corresponding hanger-pin, substantially as described.

6. In ay cai' truck frame of the character hanger brackets cast integral With the frame,

and having respectively, an. opening trans; versely therethrough,I of a metallic bushing cast in and removable from the said opening and adapted to form a bearing for thelcorresponding hanger-pin, substantially as de-y scribed.

7. In a car truck. frame of the character described, the combination'with the springbeain and brake hanger brackets cast in-` tegral with the frame, and having respec tively, an openingr transversely therethrough,

of a metallic bushing cast in and removable from thev saidv opening and adapted to form a bearing for the corresponding hanger-pin,L

substantially as described.

In testimony whereof we have signed our 'i naines to lthis specification in the presence ot two subscribing witnesses.
